How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a lightweight folding headphone built for shared listening in classrooms, clinics and assistive-listening setups, choose Williams AV Sound HED 021; if you need a tough, kid-friendly foldable headphone for a drum kit, tablet or backpack, choose ROCKSOCKI Kids.
• Williams AV Sound HED 021 — biggest strength: a genuinely packable folding design at roughly 0.12 lbs, with adult sizing, 32 Ω impedance, a mono signal and a mild / low-gain hearing-loss rating. It is purpose-built for spoken-word listening rather than music.
• Williams AV Sound HED 021 — biggest trade-off: it is a specialist tool. Mono output, no stated noise control, no media controls, and a model that has been on the market since 2001. It is not a general-purpose music headphone.
• ROCKSOCKI Kids — biggest strength: built for rough handling — a reinforced nylon-fabric cable, soft padded headband and ear pads, a collapsible frame that folds into a backpack or suitcase, and a 3.5 mm wired jack with media controls.
• ROCKSOCKI Kids — biggest trade-off: 4 ohm impedance and a kid-focused over-ear fit make it a poor match for professional or adult listening gear, and the bear-ear cartoon styling is firmly aimed at children.
• Who each is for: Williams AV Sound HED 021 for adults in assistive-listening, classroom or institutional settings; ROCKSOCKI Kids for children who need a durable, foldable headphone for a drum set, school or travel.
The HED 021 is a folding headphone in adult size, and the folding part matters more than it sounds. It collapses down for storage, and at a listed 0.12 lbs it is light enough that wearing it for a long session won't feel like a chore. The stated dimensions are compact — roughly 6-7/8" x 5-5/8" x 7/8" in its folded state — so it slips into a case or drawer without taking up real space.
What separates it from a normal pair of headphones is the intent behind the spec sheet. It is rated at 32 Ω and runs mono, not stereo, and it carries a mild and low-gain hearing loss rating. That combination tells you this is a speech-first headphone: designed to sit on a listener's head and deliver clear, intelligible audio from an assistive-listening receiver or similar system, where a single summed channel is exactly what you want. The brand also lists replacement earpads (HED 023 and HED 023-100) and sanitary covers sold in packs of 100, which is a strong hint about how these get used — shared, repeatedly, by different people, in schools, clinics, theaters or houses of worship.
So who should buy it? If you run an assistive-listening program, need a folding adult headphone that packs away, and want a model with a documented spare-parts path so you can keep a fleet running for years, this fits. The replaceable earpads and bulk sanitary covers are the real story here; they signal a product meant to be maintained, not replaced.
Who should skip it? Anyone shopping for music. Mono, 32 Ω and a mild/low-gain hearing-loss rating are not the profile of a stereo music headphone, and there is no noise control or inline media control listed. If you want to listen to albums, take calls or block out a commute, this is the wrong tool.
The ROCKSOCKI Kids headphone is a wired over-ear model with a bear-ear design, a 3.5 mm jack and a foldable, adjustable frame. It is explicitly aimed at children, and the spec list reads like a parent wrote the requirements: soft headband, soft ear pads, lightweight, and a cable reinforced with nylon fabric so it survives being yanked, twisted and stuffed into a bag.
The folding part is the practical hook. Because the frame collapses, it stores flat in a backpack, a school desk or a suitcase, which makes it a sensible travel and school headphone rather than something that lives permanently on a desk. The 3.5 mm wired connection means it plugs straight into a drum module, a tablet, a laptop or a handheld console with no pairing, charging or dongles to manage — genuinely useful when a kid wants to practice an electronic drum set without filling the house with noise.
The styling is deliberately playful: rounded-tip earpieces, a cartoon theme and the bear-ear shape. That's a feature if you're buying for a child and a dealbreaker if you're not. On the technical side, the listed impedance is 4 ohm, which is very low and tells you this is meant for the low-power outputs found on consumer devices rather than for studio or pro audio chains. There is a media control on the cable and no active noise cancelation.
Buy it if you need a durable, foldable, kid-sized headphone for drum practice, school or trips, and you want a wired connection that just works. Skip it if you're an adult, if you need noise cancelation, or if you want a headphone that looks at home in a professional setting.
Side-by-Side: Which Should You Choose?
• Best for kids and rough handling → ROCKSOCKI Kids. The nylon-reinforced cable and soft, lightweight build are aimed squarely at children.
• Best for folding and packing → both, for different reasons. The HED 021 folds to a compact adult-size shape for a case or drawer; the ROCKSOCKI Kids collapses to fit a backpack, desk or suitcase.
• Best for music and media → ROCKSOCKI Kids. A 3.5 mm wired jack, over-ear fit and inline media control suit everyday listening far better than a mono speech headphone.
• Best for longevity and spare parts → Williams AV Sound HED 021. Replaceable earpads and bulk sanitary covers mean you can maintain it instead of replacing it.
• Best for a drum set or gaming device → ROCKSOCKI Kids. The 3.5 mm jack and low 4 ohm impedance match the headphone outputs on consumer electronics.
• Best for institutions buying in numbers → Williams AV Sound HED 021. The maintenance-first design is built for repeated, multi-user deployment.
• Best for a quick, no-fuss gift for a child → ROCKSOCKI Kids. Playful styling, adjustable fit and a tough cable make it an easy pick for kids.
In my opinion, the right choice comes down to one question: are you equipping a listener or a child? If you're outfitting a classroom, clinic, theater or assistive-listening program and you want an adult-size folding headphone with a real spare-parts path, I would buy the Williams AV Sound HED 021. If you're buying for a kid who needs a durable, foldable, wired headphone for a drum kit, school or travel, I would buy the ROCKSOCKI Kids. They're not competitors so much as two different jobs.
are on ear headphones good
They can be, and it depends on the job. The Williams AV Sound HED 021 is a folding adult-size headphone rated at 32 Ω with a mono signal and a mild/low-gain hearing-loss rating, which suits spoken-word and assistive listening. The ROCKSOCKI Kids is listed as over-ear with soft pads, aimed at children's everyday listening.
what are the best open ear headphones
Neither product here is an open-ear design. Both the Williams AV Sound HED 021 and the ROCKSOCKI Kids are conventional headphones that sit on or over the ear. If you specifically want an open-ear style, you'd need to look at a different category entirely.
which are the best over the ear headphones
There's no single answer, because "best" depends on who's wearing them. The ROCKSOCKI Kids is listed as over-ear with soft ear pads, a foldable adjustable frame and a nylon-reinforced cable, which makes it a strong fit for children. The Williams AV Sound HED 021 is a lighter, folding adult model built for speech and assistive listening rather than media.
what are the best over the ear headphones to buy
Match the headphone to the use. Choose the Williams AV Sound HED 021 if you need a foldable adult headphone for shared or assistive listening, with replaceable earpads and sanitary covers. Choose the ROCKSOCKI Kids if you need a tough, foldable, wired headphone for a child. Check the current price on Amazon before deciding, since that's the factor I can't quote here.
